Latest Alan Guth Stories
The 2013 Gruber Cosmology Prize recognizes Viatcheslav Mukhanov and Alexei Starobinsky for their formative contributions to inflationary theory, an essential component for understanding the evolution and structure of the universe.
Stanford physics Professor Andrei Linde has been named an inaugural winner of the $3 million Fundamental Physics Prize.
During the next decade, a delicate measurement of primordial light could reveal convincing evidence for the popular cosmic inflation theory, which proposes that a random, microscopic density fluctuation in the fabric of space and time gave birth to the universe in a hot big bang approximately 13.7 billion years ago.
Dark energy -- a mysterious force that causes matter to accelerate away from other matter -- is a case in point. It fuels the expansion of our universe, but it's an oddly small force. But if it were bigger and caused matter to fly apart any faster, you would not be here to read these words.
Inflation -- Inflation is the idea - first proposed by Alan Guth (1981) - that the nascent universe passed through a phase of exponential expansion that was driven by a negative vacuum energy density (positive vacuum pressure). This expansion can be modelled by a non-zero cosmological constant. As a direct consequence of this expansion, all of the observable universe is posited to have originated in a small, initially causally-connected region. Quantum fluctuations in this microscopic...
